8 lbs Calcium Increaser Pouch

Low calcium hardness leads to corrosive water that eats away at your pool's plaster and equipment, making this 100.0% Calcium Chloride pouch a necessary maintenance item.
This 8 lbs Calcium Increaser Pouch from Regal is what pool techs reach for when testing reveals soft water that threatens the structural integrity of gunite or plaster surfaces. Containing 100.0% Calcium Chloride, this formula reliably handles the task of raising hardness levels to the ideal 200-400 ppm range without adding unnecessary fillers or cyanuric acid. The 8 LBS (3.63 kg) ecobag packaging is designed for easy handling and reduced waste compared to traditional plastic buckets.

Calcium chloride generates heat when it dissolves (an exothermic reaction); always add the 8 lbs of granules into a bucket of water first rather than pouring water onto the chemical to prevent splashing or container damage.
Common Questions & Instructions
How much Regal Calcium Increaser do I need for my 10,000-gallon pool?
To raise your calcium hardness by 10 ppm in a 10,000-gallon pool, you typically need 1.25 lbs of this product; the full 8 lbs pouch will raise a 10,000-gallon pool by approximately 64 ppm.
Will this product affect my pool's pH or alkalinity levels?
While primarily designed to increase hardness, adding large amounts of Calcium Chloride can cause a slight temporary rise in pH, so always re-test your balance 24 hours after application.
Is it safe to swim immediately after adding calcium increaser?
We recommend waiting at least 2 to 4 hours for the product to fully circulate and dissolve before swimming to avoid skin or eye irritation from undissolved granules.
